The solution for rugged active blind mate VPX interconnect systems

LightLightCONEXCONEXPlug-in module and backplane connectors for VPX systemsPlug-in module and backplane connectors for VPX systems

The LightCONEX® active blind mate optical interconnect is a revolutionary solution for VPX systems that includes a fixed plug-in module connector and a floating backplane connector compatible with proposed VITA 66.5 standard. The low-profile plug-in module connector is screwed on the board edge through an interposer, saving board space and eliminating fiber cable handling. The backplane connector has a spring-loaded MT to ensure a secure MT to MT mating connection under extreme shock and vibration conditions.

Key advantages• Optical interconnect: Mechanical Transfer (MT) ferrule with linear array

of 12 or 24 parallel multimode fibers• Secure connection: Spring within the backplane optical cable

provides the mating force between plug-in module and backplane MTs.• Standards: Designed following VITA 66.5 standard (forthcoming).• Maintenance: Supports two-level maintenance.• Blind mate: Eliminates fiber handling and frees up space on host

board.• Robustness: Tested for vibration and shock over industrial temperature

range, exposure to humidity, salt fog, sand and dust, mate/un-mate cycles, following military specs.

Backplane connector featuresThe LightCONEX backplane connector contains the Face plate and Insert. The connector is designed to provide float in both the X- and Y-directions to enable alignment of the MT ferrule mating interfaces. The design complies with the ANSI/VITA 66.4 mating requirements with the MT ferrule displacement occurring within the backplane connector. Single or dual MT ferrules are available.

• Spring-loaded MT ferrule (12-lane or 24-lane)• Coarse and fine mating alignment• Low profile: 10 mm height• Compatible with 12-lane or 24-lane OM3 or OM4 fiber

ribbon cable

The main components of the backplane connector are:

1. Face plates. Dedicated face plates are available for VITA 67.3 (apertures C, D, and E) and VITA 66.4.

2. Insert housing available in styles A, B, and C. The main components of the housing are:3. Primary alignment feature4. MT ferrule with alignment pins5. Optical cable assembly with springs.

Optical cable options are:12 fibers MT: 6 in. 12-fiber optical cable with MT12 termination at both ends, alignment pins, and a single MT clip.24 fibers MT: 6 in. dual 12-fiber optical cable with MT24 termination at one end and dual MT12 termination at the other, alignment pins, and 2 MT clips.
